Review: From Disappointed to Delighted! - UPDATE 7/17/18 - I am happy to change my original 2-star review to 5 stars! The first mic I got had a terrible high-end screech, and as I dialed down to the correct volume, a high-pitched digital "hiss." I played with it and could get it to reduce, but not go away. This is on a Sony RX10 Mark 4. I sent the mic back, rather than wait for an exchange, due to a deadline. To Fifine's great credit, they followed up with me. Even though I had returned the unit, they asked if I would like another one to test. Their customer service was excellent (which is why I had updated my original review to 3 stars. Good customer service is rare, and they should be recognized for it). I enjoy testing and technology, so I said that I would be willing to test another unit and determine whether I just had something wrong in the original unit, or whether the mic wasn't compatible. Today, I tested it on my interview set, using all the same settings as the lapel mic I'm presently using. I'm pleased to say that performance was stellar. Good, clean signal; no hiss. The mic element has pretty good response. I haven't distance-tested it, but I suspect it will be fine, as both the transmitter and receiver have external antennas. Unlike a lot of mics, you can change frequency as well, if there is any interference. I do have one thing I wished it had: a hotshoe mount. The receiver is strictly a box. Now I know it will be easy to get some sort of hotshoe mount bought or made and glue it on -- I plan to do that (I'll probably 3-D print it)-- not a major deal. So to sum up: Fifine took a negative experience, and turned it into a VERY positive one. The mic now works perfectly; you also get a headset mount which will be useful in some situations. The price is unbeatable. To be crystal clear: they sent this unit for me to test and provide an update. I like it so much that I will keep it, and I'll put a hotshoe mount on the receiver to make it work in the field. Definitely recommended! UPDATE 7/10: I added a star for customer service. I've been discussing the problem with them. They've been VERY supportive, and very interested in a thorough compatibility test. I'm going to try it again, and I'll update this review once I do. UPDATE 7/8: After more troubleshooting, I believe the problem is that the electronics of either the transmitter or the camera are not shielded appropriately (although I suspect the $34.95 receiver a whole lot more than an $1800 camera). I've decided to send it back - no reflection on the seller, who I haven't given enough time to respond, but I need this ready next week. ORIGINAL: I just got the mic today to connect to my Sony RX10 Mark 4 for some interviews I wanted to do. I have a Sony hotshoe mic, which has beautiful sound, but it was picking up too much reverb/echo from the room. When I connected the receiver to the camera, I immediately got a loud, high-pitched screech. I dialed down the input volume a lot and moved cables. Eventually I was able to get the background noise down to a high-pitched digital-sounding hiss. It gets dramatically worse when I turn on the transmitter, even with no mic plugged in. I tried moving the cables, changing channels,playing with the volume, but I just can't get a clean signal. It just may not be compatible with my camera. I've emailed customer service a few minutes ago; I'll give them a day or so to see what they say. Since I'm planning to do my interviews next week, if they don't respond quickly, I'll probably pick up a different brand and return this one. If the problem gets solved, I'll update the review and the stars.
Review: FIFINe Wireless Microphone Sytem is a "Winner Winner Chicken Dinner" - Disclaimer: Although I did purchase this microphone system, FIFINE did reimburse me for the cost and ask that I provide and honest review with both Pros and Cons. Here is my review and video. I was skeptical that a wireless microphone system at this price point would offer any value at all. Imagine my surprise when I heard the great sound quality this FIFINE system provides. My first impression was of the packaging. A very nice box with simple company logo on top. Inside was a well packaged system, a thank you card, and instruction manual. The unboxing experience is always a deal breaker for me and a detail some manufacturers overlook. I want it to be enticing and to get me excited to use the product. FIFINE provided that experience for me. The wireless microphone system itself felt like a quality product in my hands, although I did feel that it wasn't something I would feel comfortable with dropping on the sidewalk or hard surface as the receiver and transmitter were made from plastic. The sound quality is acceptable to use even if you don't know how to adjust your audio files. It didn't seem to reduce ambient noise but my voice was loud and clear. I would suggest positioning the mic further from your mouth than is pictured as you can not adjust the volume on the unit itself and the mic is very sensitive. I was able to step over 80 feet away from my camera and did not loose audio and the quality remained the same throughout the test. My distance test was performed in a straight line with line of sight never being broken. Battery life is dependent on the quality of your batteries so user experiences may vary. Pros: Easy to set up All cables provided Works great for the price Sound quality is very good Use straight out of the box Cons: No way to mount to camera so receiver dangles Two types of batteries needed AA and AAA Finally, I recommend the FIFINE Wireless Microphone System. You won't be disappointed in the sound quality and ease of use. Great for use for video recording or PA use. Give it a try you won't be disappointed.

## Questions & Answers

**Q: What are the exact 20 frequencies on these units please.  what is the mw output of the transmitters please.?**
A: Frequency is 565 to 584
Power 10db/10MV

**Q: I have a sony srs xb20 speaker can i use your system if i use a 1/4 to 3/8 adapter to plug into the Sony unit? if not why not?**
A: No, you can't. Because this receiver output is about the same level as a wired mic. It must be plugged into a 1/4'' speaker input designed for a mic connection. If your speaker has only 3.5mm line inputs which require a higher level signal than a mic provides, the mic will be not suitable to be used with it, even you add an adapter. The sound will be soft and hard to be heard.

**Q: Can I plug the receiver into my iPhone, audio mixer, or Mac to record the audio?**
A: Sorry, it works with only audio mixer that has 1/4" mic jack. If you need a mic to use with Mac, we have the K031 (Asin: B074C125TN) USB wireless lav mic. But neither of them will work with iPhone.

**Q: can it be used for singing**
A: It will be more suitable for speaking than singing. 
We would recommend the handheld mic K025(ASIN:B0795PNCBG) or K035(ASIN:B01MT6AAIC) for singing. All these mics need to work with speakers/amps that has 1/4'' mic input.

### ⭐⭐⭐⭐ A good budget option
*by B***S on April 13, 2020*

Microphones can easily cost hundreds or even thousands of dollars. This one is obviously a budget model and you'd be correct in assuming that you're not going to get professional quality audio from a budget microphone. If I were reviewing this on the basis of audio quality alone, it wouldn't be the one I'd recommend. If you're a professional for whom perfect quality is important, this isn't for you. The question, though, isn't whether this is the best microphone on the market (it's clearly not), but whether it's a good value for the money. Overall, I think it is. I use this primarily when I'm speaking on stage. For a public speaker, I think this is a good option. The sound quality isn't perfect, but it's pretty good. While musicians will require better audio than this can deliver, it works well for speech. I even *have* used it for recorded speech in a pinch because it's better to have a mic on my lapel than to trust the on-board microphone on my camera. However, I wouldn't really recommend it for that purpose. The quality is good, but it might not be quite as good as you want if you mean for the recording to be viewed by a public audience. I was pleased with the range I can get out of this. I tend to move around quite a bit on stage, but I've never had any trouble of audio quality dropping off (or sound cutting out) even when I get relatively far away from the receiver. It's not a perfect product, but I do recommend it for the price. It's a good budget option for anyone who doesn't need professional quality and doesn't want to pay professional prices.
